Lanthanum Strontium Cobaltite (LSC) is a highly conductive perovskite material that is often used as a “contact paste” in SOFC systems, where it creates the bond between the cathode of the cell and the current collector (often a metal mesh or plate). Our LSC powder can be easily fabricated into an ink for painting or screen printing. LSC has a relatively low sintering temperature, so it is best used in SOFCs operating at less than about 750 °C. Another design consideration for using LSC is its relatively high thermal expansion coefficient, which leads to expansion mismatches at higher operating temperatures.
